Made of aluminum foil in the offset paper with a sodium silicate material mounted, can also be printed. But the foil itself easy oxidation and dark, friction, touch will fade, it is not suitable for long-term preservation of books cover the hot stamping.No. aluminum foil, rubber, plastic packaging bags, they all contain PE, POV, POF, etc. some materials are not decomposed by soilSilent quiet good Ctrl+c autograph is prohibited

Q:Is there any harm to the pure milk packing aluminum foil in boiling water?

There is a polythene film (PE film) inside the aluminum foil package. The temperature of the ordinary boiling water is not enough to dissolve and destroy the PE film, and it will not touch the food. The boiling temperature of the water can not reach the melting point of the PE film, and the milk will not touch the aluminum foil, so the aluminum can not be detected. Aluminum is also relatively stable, it is not particularly lively metal, so simply by boiling it, it does not occur chemical reactions, and then into the food. In other words, in the case of packaging in line with national standards, the packaging of boiled milk will not lead to excessive aluminum.

Q:Relationship between capacitor capacity and aluminum foil

The capacitance C of the parallel plate capacitor is directly proportional to the dielectric constant epsilon, inversely proportional to the area, and inversely proportional to the distance d between the platesC= epsilon S/4 PI KDK is static electric constant in the formula

Q:Aluminum foil lunch box microwave oven operation method?

1. before use, please tear open the aluminum cover (open the lid, not airtight heating).2., the food should be packed with lunch boxes (at least 80% of the total capacity of the whole lunch box).3. lunch boxes should be placed in the middle of the microwave oven turntable. (Note: if your microwave oven is a metal turntable, please insert a ceramic or glass mat underneath the lunch box.)4. lunch boxes can not touch the four walls of the microwave oven. (at least leave the wall of the microwave oven 2cm)5. microwave ovens can only use one aluminum foil lunch box at a time.

Q:The working principle and characteristics of hand held aluminum foil sealing machine

The machine can be divided into two parts: the control box and the output induction head. 100KHZ high frequency current generated by the microcomputer control source by amplifying, shaping, push the power module output to the sensor head, when the metal aluminum foil container Gary proximity sensing head, eddy current heating on the aluminum foil, heating degree by the intensity and duration of the short length to determine eddy current. The whole machine is equipped with an automatic frequency stabilizing circuit, the function time can be adjusted and the working status can be displayed. This machine has been improved to slow the sealing speed of the 500A model, so that the machine can be continuously heated by heating without stopping once. Therefore, the sealing speed of the machine is much faster than that of the 500A model.

Q:What's the flow of aluminum foil statistics?

The width of the aluminum foil is cut according to the user's requirement, but the width of the rolling is different from that of the rolling mill, and the maximum is 2m.Aluminum foil varieties have roll foil and foil, and hard foil and soft foil. The aluminum foil which is directly rolled by the mill is called plain foil, and the treated aluminum foil is made of embossed aluminum foil, composite aluminum foil, coated aluminum foil, colored aluminum foil and printed aluminum foil (see coated aluminum foil). From the angle of purity and alloy variety: industrial pure aluminum foil (purity 99.7% ~ 98.8%), iron aluminum (including Fe1%), the high pure aluminum foil (purity 99.85% ~ 99.99%) and Aluminum Alloy foil (aluminum manganese alloy foil, aluminum magnesium alloy foil and hard aluminum foil etc.). Can also be classified and addressed from the use of, such as packaging aluminum foil, capacitors, aluminum foil and so on.The use and consumption of aluminum foil, aluminum foil is widely used, see Table 3, so the annual consumption is very large, for example, in recent years, the United States is about 400 thousand T, Germany and Japan for 100 thousand T or so, Britain, France and China is about 50 thousand T.

Q:Does the FFC package foil have no grounding, which is equivalent to adding a capacitor to the cable?

If both ends are not grounded, it should be equivalent to the effect of adding an inductor (somewhat like the use of a magnetic ring).If there is a parasitic capacitor, it exists everywhere, but the size of the parasitic capacitance.

Q:Hand held aluminum foil induction sealing machine, how long is the sealing time?

The hand-held aluminum foil sealing machine is a machine which uses electromagnetic induction principle to induction, heat and seal plastic, glass and other non-metal bottles and ring containers. For metal containers, do not use this machine seal.Recommend a small number of products, practical handheld aluminum foil sealing machine. It is the first choice for small businesses to save equipment costs. This machine can adjust sealing power according to sealing size. The bottle neck can be used between 20 and 100 millimeters in diameter

Q:Plastic container for food packing container

Composite film bag: made of different kinds of plastic film or laminated with plastic film and paper and aluminum foil. According to the use and requirements, it can be made of two layers, three or more kinds of composite film bags. Such as polyethylene - polyester, cellophane - polyvinylidene chloride, polyethylene two - polyethylene, paper, polyester - aluminum foil - polyolefin, polyethylene - aluminum foil - paper - polyethylene - polyamide film bags. By hot lamination, coating, adhesive, CO extrusion method for processing and preparing, with special adhesive between layers. One of the typical representatives of composite film bags is a retort pouch for high temperature sterilization. It has excellent isolation, can long-term preservation of food, not deterioration, there are soft canned. The composite material is based on polyester aluminum foil polyolefin. The composite film bag can also be applied to aseptic packaging process, and the full-automatic production line of container forming, food filling and sealing can be successfully realized by using composite material. The recently emerging boxes, bags and barrels are the first aseptic packaging containers developed in the United Kingdom for packaging liquid and mushy foods, such as wines, juices, ketchup, etc.. The packing bag is made of plastic and aluminum foil, and the volume is 5, 20, 200, 220 and 1000 liters. Filling under aseptic conditions, into the corrugated box (5 ~ 200 liters bag) or wooden box (1000 liter bag), called the box into the bag; if the drums (220 liters), it is called barrel bag. Its common feature is convenient storage and transportation.

Q:How aseptic packaging aluminum foil bag?

Aluminum foil bag is a major cause of the two pollution products after sterilization, disinfection quality of packaging damage to chemical or physical methods of conventional microwave disinfection than conventional heating disinfection required low temperature, a great impact on the quality of the product will not. The use of microwave technology in soy sauce packaging bags to prevent halogen, can prevent soy sauce due to packaging caused by the two pollution problems, and prolong the shelf life of bagged products. In the case of plastic bag sterilization, mainly for sealed aluminum foil bags.
